To understand the date and context of this picture, as well as that "us again" refers to Damaris Cerdas and Pedro, cf. picture 89.
Nevertheless, the exact date mentioned in the original caption of picture 89 (Tuesday 15 June 1993) cannot be correct, as the volunteers only left Makira on 21 June 1993 (cf. picture 93), presumably only then going to Honiara. The first dated photograph which mentions having returned to Honiara is dated 24 June 1993 (cf. picture 95). The photograph must have been taken somewhere in June 1993, but not earlier than the 21st.
Original Spanish caption to this photo:
Nuevamente nosotros con el Gobernador de las Islas George D.P.
Us again with the governor of Solomon Islands, George D.P.

With thankful credit to Damaris Cerdas (a Costa Rican citizen who photographed and annotated her volunteering experience to the Solomon Islands in 1993) for having given me permission to digitize her photo album (August 2016) and publish 98% of it under a Creative Commons BY-SA 4.0 license, which I have done here.
As for your interest to know who of the volunteers went on to careers in aid and development: picture 100 shows a volunteer named Mark Kelly (on the right-hand side of the picture). There exists a Mark Kelly who seems to be from Denmark, lists Solomon Islands as a country where he had work experience, who became Senior Director Operations - World Vision South Asia & Pacific in 2010, and then went on to become the National Director - World Vision Zambia in 2015. Nevertheless, I have a hard time confirming that he is the same Mark Kelly, based on the picture at his LinkedIn (Denmark) page.
Louise Vella recently pointed out to me that Youth Challenge Australia is now known as VOICE. Via this helpful remark, I found out that the right-hand side of the same picture 100 is presumably Mark Darby:
"Mark Darby, a University of Technology Sydney (UTS) lecturer, was involved in Operation Raleigh and he returned to Australia full of passion, energy and enthusiasm to undertake more programs overseas. Many of his fellow participants from around the world in Canada, Australia and Costa Rica felt the same and together they established Youth Challenge International (YCI) in Canada in 1989" (copied from: Who we are, VOICE, accessed at 25 August 2016).
If you would happen to recognize anybody in the pictures, please feel free to let me know.
August 24, 2016 Subject:
Governor General George Lepping
The Governor General's name was Sir George Lepping GCMG from the Shortlands who was G-G from 1988-1996.
I was working with Save the Children Australia in the Ministry of Health and Medical Services in Makira at the time and was pleased to be involved in the Youth Challenge International programs in 1992 and 1993.
It was an excellent program and opportunity for volunteering, quite a number of whom went on to careers in aid and development. It would be interesting to find out who did.
Well done for making this series of photos available - it's a very evocative memory
